Not all of it, only the VIRTUAL clock which is
if (use_icount) {
return cpu_get_icount();
} else {
return cpu_get_clock();
}
and would be changed to something like
return cpu_get_virtual_clock();
In turn cpu_get_virtual_clock() is
return (accel_ops->cpu_get_virtual clock ?: cpu_get_clock)();
in the emulators, plus a stub that replaces stubs/cpu-get-icount.c and
is just
return get_clock_realtime();
as in stubs/cpu-get-clock.c.
